107 Claims.

My invention relates to apparatus by which fastenings are supplied in loads of one or more in number to a machine by which such fastenings are to be inserted, it being especially directed to 5 the delivery of nails or the like in successive groups, from a mass contained in a receptacle forming a part of a distributor vand advanced therefrom by the loading means of this apparatus to the receiving machine.

is dilcult to insurey their delivery'by automatic means in full groups or loads. When a load with a missing nail crnails is ied into a loading device for transfer to a machine for attaching heels to shoes, it is necessary that incomplete loads bel noted, and the defect corrected. Ii this is not possible, the Work produced is faulty. If each load can be inspected, and the missing nails supplied, it produces a substantial loss of time. yIt is an object of my invention to guard against the delivery of a partial load. In the attainment of this object, I test each load or group of fastenwhich the apparatus itself has determined to be 0 missed. Under no conditions can a partial load be fed. Preferably, a distributing or loading member, as an oscillatoryroll provided with a fastening-receiving passagesupplied from a raceway, temporarily holds the fastenings during their delivery to the machine to besupplied. A cooperating testing means or feeler, aiected by the absence of a fastening or fastenings at the holder, controls their delivery and the-operation of the machine to be supplied, thus preventing their use. o fhe roll or other holder is preferably movable 1n a casing having delivering, receiving and test-k ing openings for the fastenings, into registration With which openings the holder-passage may be moved. In this movement, the holder may invert the fastening contained in the passage. To determine the position ofthe holder-roll, a device, as a rotatable cam, is provided for controlling rotation to certain of its positions, as those for. receiving and testing, there being associated with 50 this device other means for turning the roll toits delivering position.` A member movable 'by the operator controls the rotation of the roll through the oscillation of a primary lever, and the other means by which the roll is turned is governed by a member movable` through a secondary lever in rik the control of the machinesuppliedv With ias- 60 it releases for the shifting of the fastening-roll Because of irregularities in the form of nails, it

'holder-roll is rotatable. the opening, .whereupon movement Aof the .rod

carries the nail into the'roll-passage and forces fromthe testing to the deliveringposition. In'

TENT oFFICE- j l y the illustrative form of the invention, the con' trolling means for the testing member consists of two disks, one'rotatable with or as a part of the holder-roll and the other rotatable 'relatively -thereto.= In the periphery of each disk is a depression, and when these depressions are in registration, a lever or likememberracting upon the feeler or feelers may entersaid-depressions y.to

and prepares for the rotation of the roll after the I testing has been performed. Whenthe feeler fails to find a nail in the passage, it actuatesv a stop'member, which both prevents operation of the machine rwhich the apparatus supplies and, the movement of the disks or other controlling vmeans Which would permit fastening-deliveryf from the roll. T he inserting operation therefore cannot proceed until a full load of nails is ready yfor delivery. To facilitate the introduction into the holding-passage of a missing fastening, a loading member movablebyrthe operator is prof' vided. The holdingepassage preferably extends through the roll, and the automatically operated Atesting means is movable into one end thereof,

While. at the opposite end, the manually operated loading means may introduce fastenin'gsinto the i passage.

rocate' in an opening in the casing in which the A slot admits a nail to out vthe feeler, which found `Such passage empty. In its inward' position, Which visl the normal or operating relation, the loader-rod is latohed.` Means movable with the rod closes the fastening-- receiving slot against the entrancey of dirt in this normal position. To guard against the delivery of a double load of fastenings by the apparatus,

the operator-actuated -member, which controls y the movement of the holdingand delivering mem-- ber and of a transferring device, has means for locking it against movement by the operator, this plied by the apparatus. i As particularly disclosed herein, a rotatable cam operates. the nail-roll through a lever which initially is `out of engagement with the cam andwhich is governed by a hand-lever. A look retains y the` .hand-lever against movement under the controlv of thecamlever in its initial relation, and this lock is re,`

moved when the .cam-lever is released for engag'ement With the cam." The release is eiected in the control of the machine supplied, so `the delivery of a load of nails may be produced only after the machine has utilized the preceding load.

Another object of the invention is to maintain 5 from a mass of nails or other fastenings in the distributing portion of the apparatus, a regular supply, by simple and effective means, and in such a manner that a plurality of sizes may be fed simultaneously. For this purpose, there is 4rotatable in a stationary receptacle disks iixed to a shaft and provided with elevating buckets delivering to raceways, these buckets being shown as staggered upon opposite sides of the disks. 'I'he disks divide the receptacle into separate compartments, in each of which fastenings differing in size or form from those in other compartments may be held. A cover is shown as hinged upon the receptacle, having a portion extending over each of the one or more raceways to protect' 2,0 these. To free the raceway or raceways from crossed fastenings, rotatable clearing means is carried by the cover, gearing which turns the shaft and disks also rotating the clearing means.

`A further object of the invention is to pick off accurately, one by one, for delivery from each raceway, successive fastenings. For this purpose, I employ a member movable at the end of a raceway and having a ilexible projection arranged to engage the terminal fastening and separate it from the raceway. This projection is preferably in the form of a spring-wall, which is at the outer side of a recess in the wall of an oscillatory cylinder contained in a casing at the end of the raceway. 'I'he fastening-engaging end of the projection is inclined downwardly and rearwardly with respect to the direction of separating movement. Such a separator will yield without clogging or breaking, if it does not engage the fastenings in the best relation, and will gradually straighten fastenings which have become inclined from the vertical. In its separation, a fastening enters a space between the end of the outer or flexible wall and the wall furnished by the recess in the cylinder and is drawn off from the raceway by the outer wall. 'I'he fastening is then carried by the end of the recess to a delivery-opening in the casing, such opening being larger than the head of the nail. Each of the separating cylinders for plural raceways is rotated by a yieldable connection between it and its actuating means. In the present instance, there is a toothed member, as a rack-block, meshing with the teeth upon each cylinder, there being a reciprocatory actuating member common to the toothed members. The movement of the common actuating member is transmitted to the various toothed members or blocks through springs, so breakage is avoided if clogging occurs. I have illustrated herein a cover for each of the casings enclosing the separating cylinders, this cover being hinged upon the projection from the receptacle-cover, which extends over the raceway.

The body or frame of the apparatus may be in the form of an integral casting having a baseportion I0, by which it is mounted upon the top of the frame of the heeling machine F, the jack of which is to be supplied with nails in successive loads. Above the base is a semicylindrical trough I2 (Fig. i), which provides the lower half of a nail-drum or receptacle of a distributor. At the forward side of the trough are downwardly inclined extensions I4 spaced from one another,

upon which raceway-bars I@ are secured. From the forward extremity of each portion I4, Shown therewith as a part of the base-casting, extend short, horizontal arms I8. In each of the arms is a vertical bore furnishing a casing 20 to receive a separating cylinder and horizontal bores 22 in depending portions 23 of the arms, the latter bores having rotating within them a nail-roll common to all. The cylinders and roll will later be described in detail.

Pivoted at 24 upon the trough I2 is a coverportion 26 for the nail-receptacle, this being exl tended forwardly at 28 to furnish covers for the projecting ends of the raceways. A springplunger 2l, yieldable upon the cover and entering either of two depressions in a lug 29 projecting from the trough-portion, retains said cover in either its open or closed position. Rotatable in standards 30, 30 at the ends of the nail-receptacle is a shaft 32 having secured to it pairs of circular plates 34, 34 situated at opposite sides of the inner ends of the raceways, the peripheries of these plates moving in close proximity t0 the interior of the trough and cover. The outer plates of the entire series furnish closures for the ends of the receptacle. At the opposite faces of the plates, within the receptacle, are secured buckets 36, inclined in the usual manner to lift the nails from masses contained in the compartments between the plates and drop them on upwardly diverging retaining walls 38, se-

cured to the opposite sides of the raceway-bars I6. The sets of buckets on the plates may be staggered with respect to each other, to reduce the weight of the nails lifted simultaneously and therefore the load upon the driving mechanism.

Each compartment between the plates 34 may contain nails differing in character from those in the companion compartments, or the division of the receptacle may be utilized to reduce the mass which would be held together in a continuous receptacle. When the nails are to be changed, they may be removed through doors 39 pivoted at the bottom of the trough I2 and individual to the respective compartments. The

driving of the plates and buckets may be effected f by a gear 40 fast upon a horizontal shaft 42, which is driven from a main vertical shaft 46 and a vertical countershaft 45, through spurgearing 41 and worm-gearing 49. The gear 40 meshes with a large gear 48 secured to the shaft 32, the movement being in the direction of the arrow in Fig. 1. The gear 48 also meshes with a pinion 50, upon a shaft 52 journaled upon the cover 26 and having a second pinion 55 meshing with a pinion 54 upon a shaft 55 also rotatable upon the cover. On the shaft 58, which extends the full width of the cover, is a series of toothed clearing disks 58, one of which is furnished by the pinion 54. These disks turn in close proximity to the upper surfaces ofthe raceways and act to sweep back into the receptacle crossed nails which tend to interfere with the advance of the nails properly hanging by their heads upon the bars |6.

Referring particularly to Figs. 3, 4, 5 and 10, I have arranged to turn in the casings 20, cylinders 60, one for each raceway-slot. The cylinders are protected, with capacity for ready access to. them, by individual covers 82 pivoted at 94- on the coverportions 28 and having nger-pieces 66 by which they may be thrown back. On the periphery of each cylinder are gear-teeth 88, with which meshes a rack-block 'l0 guided in depressions in the ends of the arms I8. series of blocks passes a spindle 12, in which are recesses, each containing a compression-spring 14. One extremity of this spring abuts against the end-wall of its recess, while the other contacts with a projection 7B from the corresponding rack-block 10. Thus, when the spindle is moved to the right, as viewed in Fig. 3, the rack-blocks yieldably turn the cylinders 90 in their casings. As best shown in Fig. ll, each cylinder 90 has a slot 80 formed between a vertical wall 8| of a recess in the side of the cylinder, this wall being curved inwardly and rearwardly, as said cylinder is rotated for delivery, and an outer wall provided by a spring separating finger 82 secured to the cylinder at 84. Normally, an opening at 86, between the end of the spring-wall 82 and the cylinder-wall 8|, is alined with its raceway-slot. As the nails descend each raceway-slot in a series, that leading is received by this space 88, and as the cylinder turns, the forward edge 90 (Fig. 5) of the spring-wall separates the nail from those succeeding it in the raceway. As therotation continues, it brings an enlarged end 92 of the slot 80 against the nail and transfers it to an opening 95 through the bottom of the casing 20. The diameter of both the vertical openings 92 and 94 is such as to pass the head of the nail. The yieldability of the wall 82 guards against breakage if the edge 90 does not strike accurately between nails, the wall being deflected somewhat as pressure is applied by it. That outward deection may not be interfered with, the ends of the raceway-bars are relieved or concaved at 93. The edge 90 of the wall 82 is curved downwardly and rearwardly. If the shank of the hanging nail happens to be displaced inwardly from the vertical, this edge will have a gradual straightening effect, drawing the entire nail into the slot 80 as it removes it from the raceway. To guard against the terminal nail being jarred rearwardly along the slot 80, so two nails might be received by the cylinder at the same time, a projection 95 from the raceway-bar at the side from which the spring-wall approaches, extends into a circumferential slot 9! in said wall and in the cylinder. This positively prevents such displacement. In the bores 22 in the arm-portions 23 of the basecasting, a nail-holding and nail-inverting roll 9B turns. lThrough this roll is a passage 98 for each of the cylinders 60. Each passage passes through the roll and in its rotation may be alined Through the entire with the casing-opening 94 in a receiving position; with a casing-passage 99 leading to one of a set of nail-tubes |00 (Fig. 7) in a delivering position; and horizontally in registration with one of a set of testing passages |92 in the casing (Figs. 6 and 8). manner to be described, a cam |04 (Figs. 2 and 3) upon its end engages aprojection |96l on the spindle l2, reciprocating this and causing the oscillation of the cylinders 60. The movements of the roll and cylinders are so synchronized by this connection that as the nails are picked fromv the raceways by the` spring-walls 82 and are dropped through the openings 94, they will bev received by the roll-passages 98, which at that time register with said openings.

To rotate the nail-roll 90, a lever |08 (Figs. 1 and 6) is fulcrumed beneath the trough |2 to turn about a horizontal spindle H0.` This'lever has two arms H2 and H3. The arm ||2 carries atv its forward extremity a gear-segment H4 meshing with a pinion H6 fast upon the roll. A rod i8 joins this arm to a bell-crank-lever |20 which oscillated by a cam |22. During the operation of the apparatus, the periphery of the cam will engage a roll |23 upon the lever, but, initially, the roll is separated from thecam by means which will later be described. 'Ille operation of this cam may be as in the loader-controlling mechanism oaf Letters Patent of the United States No. 1,785,928,l Benjamin, December 23, 1930, except that it is formed to serve the purposes of the present, organization. A. spring |24 holds the rod le normally down, to be elevated by the cam when a hand-lever |26, fulcrumed at |28 upon a bracket projecting from the frame of the heeler F, actuated by the operator against the force of a spring |29 (Fig. 3). The contour of the cam is such that the nail-roll may be turned from an initial testing position (Fig. 6), with its passages 99 in alinement with the casing-passages |02, to

a delivering or advancing position in registration with' the tubes |00 (Fig. 7), then reversely into receiving relation beneath the openings 94, and finally with a contained load of nails back into alinement with the testing passages |92. Secured upon the end of the nail-roll is a ieeler-controlling disk |30 (Figs. 2, 3 and 6 to 8), which has in its periphery a depression |32 to receive a roll |34 upon a lever |36 fulcrumed upon theforward extremity of an outer trough-extension I4. At the opposite or inner extremity ofthe lever is a gear-segment |38, which acts on a pinion |40 fast upon a horizontal shaft |42 journaled beneath the trough-extensions. At one end of the shaft is a collar |44, and this collar is joined to the adjacent trough-extension by a torsion-spring |96. The effect of this spring is to urge the shaft in a clockwise direction, as viewed from the right of the apparatus, and through the gearing |38, M9 force the roll |34 against the periphery of the disk |39 and thus cause said roll to enter the depression |32 when the latter registers with it. For each of the passages 99 in the nail-roll there is a pinion |48 on the shaft |42, this being'connected to the shaft yieldably by a torsion-spring |59 (Fig. 10) joined to the pinion and to a collar |52 secured to the shaft. The rotation of the pinion upon the shaft under the iniiuence of the spring is limited by a slot in a collar |5| fast on the shaft, into which slot extends a projection |53 from the pinion. Each pinion meshes with a horizontally movable rack 59 upon a feeler-rod |58 mounted to reciprocate in the corresponding passage |02 (Fig. 6).. Consequently, when the As the nail-roll .is driven, in a roll |34 enters the depression 32, the feeler |56 is yieldably projected into the alined nail-rollpassage 68 to test for the presence or absence of a nail. 1n so doing, it determines the position of a stop |66, which is movable by the corresponding pinion |48 in mesh with a rack |62 upon the stop. Each stop is guided by a stud |63 projecting from one of the arms |4 of the drum-casting for inclined downward and rearward movement between the corresponding collars |5| and |52, as may be seen in Figs. 1 and 10.

Projecting from the hub of the lever |08 is -a lug |64 arranged for contact with a lug |66 upon the hub of a lever |68 (Figs. 6 and '7). Because of this relation, the levers |08 and |68 may either be turned separately or together. The lever |68 may be considered as a compound structure formed by projections from the spindle ||0. In addition to the lug |66, there is a series of projections |16, one for each of the stops |60, and two arms |12 and |13 provided with respective gear-segments |14 and |15. The segment |14 meshes with a pinion |16 xed upon a shaft |11 journaled transversely of the base I0. Also fast upon the shaft |11 is a pinion |19 engaged by a rack |13, movable horizontally by a link |80 connected to an arm |82 mounted to turn about a spindle |84. Also turning about the spindle is an arm |86, which is joined to a rod |88 connected to the treadle of the heeler F. When the rod is raised, as a consequence of the depression of the treadle and prior to the tripping of the heelerclutch, a face |81 upon the arm |86 y presses against a face |89 of the` arm |82. This moves the rack |18 to the left (Fig. 6). The segment of the lever-arm |13 meshes with a pinion |9| rotatable about a portion of the nail-roll 36 and has turning with it a disk |92 in close proximity to the disk (Figs. 3 and 6). As best illustrated in Fig. '1, this disk |92 is provided at its periphery with a cam-wall |94 leading to a terminal-portion |95 which corresponds in depth to the depression |32. When the depressions |32 and |95 are in registration, it gives an opportunity for the roll |34 to enter them, so the lever |36 will be moved by the spring |46. This, through the gearing |38, |40, |48 and |54, will produce the testing action of the feelers |56. If these feelers, as they are moved into the passages 98 in the nail-roll 98, iind all of these supplied with nails, such feeler-movement is arrested, as appears in Fig. 6, and the stops are retained by their racks |62 above the ends of the projections |18 from the spindle ||0, which projections form a portion of the lever |68. Therefore, said lever may be turned upon elevation of the treadle-rod |88, as already described. During rotation of the shaft |11 caused by this movement of the treadle-rod, it is turning a cam 206, which is fast upon it, carrying a circumferentially extended surface 203 upon said cam along a roll 262 upon the depending arm ||3 of the lever |138. The contour of the cam |22 is such that at the beginning of a cycle, the spring |24 tends to cause the lever |08 to remove the nailroll from the testing position which it should occupy. The cam 200, however, by engagement with the roll 202, initially retains the lever |08 against movement and the roll |23 spaced from the cam |22 (Fig. 6), with elements in the testing relation in spite of the influence of the spring. The pinion |19, in addition to rotating the cam 200 to produce the effect just stated, under the influence of the rack |18, is operated to shift the rack in the opposite direction. This is eiected from the cam 22, byway of the lever |20, the rod H8, lever |08 and its projection |64, the projection |66 of lever |68, gearing |14, |16 and shaft|1'|. The arm-surface |89, from which the surface |81 became separated upon the retraction of the treadle-rod |88, is thus restored to its active position, the lost motion between the two surfaces being taken up. This movement occurs from the point at which the rack was left after the previous treadle-depression.

Considering now a complete operating cycle of this nail-supplying apparatus, there is at the termination of the preceding cycle a load of nails resting upon the drivers in the jack of the heeling machine F being supplied, ready for insertion, and there is another load in the passages 98 of the roll 96, their heads lying toward the rear. The loader-block L of the heeler is beneath the foot-plate P at which the nail-tubes |60 terminate, the loader-block-shutter l being closed. The roll 96 is in the testing position, as appears in Fig. 6, the depression |32 of the roll-disk |30 and the depression |95 of the disk |82 are in registration, receiving the roll |34 of the lever |36; and the feelers |56 are within the roll-passages. The plates 34 in the nail-receptacle l2, 26 are in continual rotation, their buckets 36 supplying nails N constantly to the raceway-slots, these nails hanging -by their heads upon the bars I6 in unbroken series. Each series is held against advance by the wall 8| of the slot 80 in the corresponding separating cylinder 60. The operator places a shoe upon the jack of the heeler, applies a heel to the heel-seat and depresses the treadle of the machine. As in Letters Patent of the United States No. 1,855,405, MacKenzie, April 26, i932, this brings down the pressure-abutments upon the heel to clamp the work upon the/jack. The nal effect of this treadle-action is to trip the heeler-clutch, so the drivers rise in the jack and force the nails which they carry through the heel-seat-material into the heel. There is, however, an interval during which the rod |88, elevated by the treadle at this time, may act upon the distributor to cause the delivery to the waiting loader-block of the nails contained in the roll-passages 98. First, however, the feelers |56 must be withdrawn to release the roll for its dumping movement. The rising treadle-rod forces the arm-surface |81 against the opposed surface |89 of the arm |82. This shifts the rack |18 to the left (Fig. 6), rotating the shaft |11 and turning the lever |68 anticlockwise to lower its segment |15. By this segment, the disk |62 is rotated clockwise to the position shown in Fig.

l'1, its depression |95 leaving the depression |32 ofv the disk |30, with which it is initially alined, and its cam-surface |94 forcing the roll |34 of lever |36 out of the depression |32. The lever |36, acting through the intermediate gearing, withdraws the feelers from the passages 98, leaving the roll free. This is on the assumption that -the load of nails in the roll-passages was com- |60 would have been in the path of their projecf tions |18, and the operator would have found the treadle locked against movement. Because of this, movement of the feeler-controlling disk |92 would be impossible, and the nail-roll would also be locked by the feelers.

Looking at the A,

gili zme'ehamlsm, he would observe from the positions of the stops which of the nail-roll-passages were empty. Horizontally alined with each testing `passage |02 in the casing surrounding the nailby a latch 2 |'6 pivoted on a collar 2|'| at the outer extremity of the rod, but may be released and retracted manually, freeing a slot 2|8 in the top of the projection 2|3 and opening into the passage 2|2. The slot is of the proper form' to receivela nail with its head at the inner side. A nail having been introduced through the slot into each empty passage, the corresponding rod or rods 2|4 are forced in and latched.- This carries the nail into the nail-roll-passage, the end of the rod furnishing a closure for the opening in the casingthrough which the introduction Was made. A guard-bar 2|9, projecting from the collar 2ST into the slot, maintains said slot normally closed and holds the collar and latch against rotation-about the axisof the rod. The

missing nails thus being supplied, the stops |60 will all be retracted. This unlocks the treadlerod- |83, which` may be elevated in the actuation of the heeler F. The unlocking of the nail-roll by the withdrawal of the eelers results, prepar-4 ing for the delivery of the load of nails fromk the roll. v

During the withdrawal of the feelers following the successul depression of the treadle, the surface 2&3 of the cam 299 has been traveling along the roll 222 in a clockwise d-irection (Fig. 6) under the influence of the rack |18, the lever |68 being. turned anticlockwise and the position o'f the lever 28 remaining unchanged. The lug |95, in the movement of the lever |68, has arrived in proximity to the lug |64 of theresting lever |08.

Now, as the rack H8 approaches the end of the movement produced by the treadle-rod |88, the surface 263r of the cam 299 passesrom and frees the roll 202 of lever |08'. The spring |24 acts upon the lever |98, this being permitted bythe -initi'al spacing of the bell-c-rank-roll |23` from the cycle, and the nal treadle-depression causes the opera-tion of the nailing mechanism to attach the heel to? the, jacked shoe by the previously delivered load ci nails. Upon release ofthe treadle by the operator, the customary spring restores its rod |89' to the normal position, but, since the surface E81 oi the arm Hit` moves away from the surface 89 of the arm |82, the rack |18 and the elements directly governed by it are left in the relation shown in Fig. 7. Here, it will be seen that the lever-arms |i2 and |73- have turned together in an anticlockwise direction, the nail-roll S' and its disk |39 and the disk |92' rotating together clockwise, with the' depressions |32I and |35 remaining in the spacedV relation in which they were left after the withdrawal of the feelers A|556 fromI the passa-ges inthe nail-roll'.

The operator takes the heeled shoeV f-ror'ni the jack and tl-iehand-lever |125- is'l -to 5 transfer te the jack the 10aa of nails contained in the loader-block and tol produce the movement of the nail-roll, rst to the nail-receiving position and then to `the testing position, where it controls the testing of the load. The clutch, gear and friction=drive mechanism Cassociated with lthe hand=lever, as in the' Benjamin' patent, actuktites the loadereblock. AIt also rotates the' cam |22 through 360 in the direction of the arrowA in Aing. 6. This raises` the rod I i8, causing the segment H4 of lever |08 to turn the naileroll anticlockwise to a position in which its passages 98 register witnthedpenings 94 of the casings 20. With the' nail-roll, the separating cylinders 60 are receiving movement yieldably through' the |04 and the connections which said cam actuates. fit each cylinder, the spring-wall 82 entiers between nail whichv is in the open endy of the slot 9|) vand theY next nail, which is in the raceway-slot, and picks 01T the former,

the end-wall of the' 'slot at 92 transferringthe separated nail to the casing-'opening 94. The

`i'ric'ivem'ents ofthe separating Vcylinders and the nail-roll areso' synchronized by theirl actuating mechanism that, as each nail falls through an opening 94, it indsv` one ofthe passages 98 in the roll ready to receive'ijt, and this it enters point down". Because of the engagement of the lug |641 with the lug |96, the lever 68 is turned with the lever |98'. Insthisrotation, itsmsegment4 |14 turns the shaft |11 and the cam 299 vanticlockwise to bring theI cam-surface 293 into' the path which'the roll 292 follows, when the lever |08 moves anticlockwise'. At the same time, the pinion |79 restores the rack |18 to its normal position with the arm-surface |89 against the armstirface |87. With the roll-'passages 98 in their `nail-'receiving relation, the depression |95 of the disk |92- is in its initial position, while th'e depression |32'of the disk |30 has been carried. beyond normal. The load of nails having been delivered to the roll, the contour of the rotating cam |22 allows the spring |24 to lower the rod ||'8 and, it, the segment ||4 of the lever |08, the lever |88 being left at rest, with the segment |15 in itsposition of maximum elevation. 'Ihe nailroll 9G is shifted clockwise by the segment |`|4 from the receiving position to' the` testing position of Fig. 6', the lever' |08 being limited in its movement by the engagement of its roll'292 with the cam-surface- 293. Simultaneously, the disk |39 is turned with theV rol-l, so' its' depression |32 again comes into registration ywith' the' depression |95' inv the now stationary disk |92. Theroll |34 `of the lever |38 is freed, so said lever: is rotated anticlockwise by the spring |46, producing the testing action' of the feelers |58 in the nail-roll- 'passages 98. Depending upon whether the' load in the roll is complete or incomplete; vthe tr'eadlerod |88 of the heel'er is' either free for'actuation or is locked by a stop or stops |1569. In the' latter case, the nail-roll is locked .by the feeler's in the passages. 'Actuation of the hand-lever |26' would' merely causethefrictionin thedriving mechanism C to slip; The cycle is now" terminated, and the elements are' in the relation .illus-- trateduin Fig. 6?.

Thee'is further furnished an arrangement: by which a' doublev delivery of nails tothe loaderblock isv additionally guarded against duringv la single operatingr cycle; This is: illustrated in Figs. 2,- 6' and '7.` In considering `this pcirti'oni of theAv apparatus,` it is to be notedv that,y at 'the beginning of a cycle,-tlie lever ZUisheIdaWjy'r-m the cam |22 because of the retention off-the 75 155 ing means and the machine supplied for testing lever |08 by the cam 20|).` This position of the lever |20 is utilized to force a spring-pressed pin 222, which is carried by a rearward extension 224 from the lever |20 and guided in the framebracket, into a depression 226 in a surface 228 on the upper side of the hand-lever |26, adjacent to its fulcrum |28. This is as appears in Fig. 6, the hand-lever being found locked if the operator attempts to move it. Upon actuation of the treadle and the release of the lever |08 by the cam 200, the spring |24 turns the lever |20 anticlockwise until the roll |23 contacts with the cam |22. This lifts the pin 222 from the depression, unlocking the hand-lever. A heel having been nailed on a jacked shoe as a consequence of the operation of the treadle, and the completed `work removed from the jack, the operator may shift the hand-lever to cause the delivery to the jack by the loader-block L of the nails which were received by the latter from the nail-roll 96 upon the treadle-depression. The hand-lever is held in its actuated position by a rotating surface 230, while the cam |22 turns through 360, as in the previously mentioned IBenjamin patent. The cam, acting upon the lever |20, again forces down the pin 222, but the movement of the hand-lever has carried away the depression 226, so said pin rides on the lever-surface 228 without interference with the movement of the lever. At the termination of the cycle, the lever |26 is released from the surface 230 and returned to its initial position by the spring |20, and when it arrives there, the pin enters the depression to again lock the lever. Therefore, the operator cannot shift the hand-lever to produce another nail-delivery or a nail-transfer until the preceding load has been driven out of the jack. In connection with the control of nail-delivery by the feelers |56, this locking of the lever has at least two advantages. The clutch of the mechanism C cannot be engaged, and therefore no harmful force can be applied to the feelers by movement of the nail-roll 96 under the power of the apparatus. Then, since the operator cannot move the handlever from its normal position, he is more promptly notied that there isa condition which must be corrected, and there is economy of effort.
